Use the zero property to determine the solutions for (2x + 6)(x - 7) = 0.
Nuetrik [128]

Answer:

x = -3

x = 7

Step-by-step explanation:

If either term is zero the product is zero

(2x + 6)(x - 7) = 0

2x + 6 = 0

2x = -6

x = -3

x - 7 = 0

x = 7

Q # 6 please multiply help
Mkey [24]
This is a problem of Difference-of-squares. We know that for a difference of squares a^2-b^2 the factorization is given by:

(a-b)(a+b)

To learn this you need to remember that a <em>difference</em> means <em>subtraction.</em> So applying those concepts we can solve this problem step by step.

Applying distributive property:

(2n)(2n-2)+2(2n-2)

Applying distributive property again:

4n^2-4n+4n+4

Simplifying:

4n^2-4

<em>The correct answer is C</em>

I need help thank you
Juliette [100K]

Answer:


Step-by-step explanation:

The key and the most critical step is to draw the line first. Don't do anything else before that.

(2,-8) (-2,-8)

What you find out is that the y value is always - 8.

So the line has no slope and any x value

y = 0*x + b

y = - 8 is the equation of the line.

Identify the initial value and rate of change for the graph shown. A coordinate plane graph is shown. A line is graphed that pas
egoroff_w [7]
Y int at (0,4).....thru points (4,1)
slope = (1 - 4) / (4 - 0) = -3/4
initial value 4, slope(rate of change) is -3/4 <==
=======================
y = 22,000x + 40,000
=======================
y = 12x + 48
slope(rate of change) = 12
=======================
(1,10)(2,8)
slope = (8-10) / (2-1) = -2/1 = -2

y = mx + b
8 = -2(2) + b
8 = -4 + b
8 + 4 = b
12 = b

slope(rate of change) = -2
initial value = 12
I am not getting any of ur answer choices ...
======================
y = x + 6
initial value = 6
